Application led September 6, 192'?. `Serial No. 217,738.

llhis invention relates to swings, and more particularly to a swing1 ofsimple construcf tion and portable nature, designed to afford healthfulbody developing` exercise, as well as amusement and pleasure.

itin` object of the invention is to provide a frame constructiondispensing1 with the use of bolts and other-fastening devices and pro`vidinp,` a lmoclodown7 construction which may be easily assembled andwhich, when assembled provides a rigidlyinterloclied frame. inaccordance with this object, a feature of the invention consists of aframe having side and cross members with uprights at their junctions,said members and uprights beingl interjoined by mortise and tenen. Addrtionally, and as a further feature, a wedgingj;l interlock is providedfor a member so joined.

fl. further object ofthe invention is to provide a suspended swing whichmay be hung low for the use of children and which is provided with armand feet inge'rating` means to provide healthful exercise andactuating,1 means for the swing.

A consideration in t-he manufacture and sale of all swings is theirdemountability, packing space and ease of assembly, since all theseelements enter into the cost and market# ability of such devices. lt istherefore an object of my invention `to provide a complete demountableor knock-down swing, requin ing a minimum of work in assembly anddispensing., to a large extent, with the use of nuts and bolts whichjareoften lost in transit and are often hard to replace in the particularsize used.

The described and other features and advantages will be more fullyapparent from the following detailed description when read in connectionwith the accompanying drawings forming part thereofand in which:

Figure l is a perspectiveview of the assembled swing,

Figure 2 is a longitudinal section on the line 2-2 of Figure l,

Figure 3 is a bottom plan view of the frame and corner uprights, only,assembled,

lfigure 4 is a detail of the mortise and tenon joint and interlocking1wedge means of the frame members and uprights,

Figure 5 is a top plan view of the swing carriage proper, detached,

Figure 6 is a detailed view of the rear swing actuating` crank hanger. p

Referring` to the-drawings by numerals, l indicates the side members ofa rectangw lar frame, and 2, the cross members `of this frame or base ofthe swing. From the junction ofthe side and `cross member of the swing,uprights 3 are provided, from the upper ends of which the swing properis suspended by means of hangers journalled at their upper ends as willbe later described.

The side and cross membersof the base frame of the swing.;r and theuprights attheir junction are interjoined into a rigid frame without theuse of securingr devices such as screws or bolts as follows: The lowerends of the uprights are provided with vertical slots 4 thereinsubstantially centrally thereof and have one edge formed with a wedggingbevel 5. The slots 4 of the uprights embrace short ribs 7, acting astenons 7 and mortises 4, the ribs 7 being formed by mortisingj or chan`nelling the oppoiste sides of cross bars Q. forming mortises with whichthe lower ends of the uprights 3 at opposite sides of the slots 4engage. The cross bars and uprights when thus-joined are seated on andlocked to the side bars l by means of the following); structural.features. The side bars, adjacent to their ends are channelled on theirinside faces as at 9 and are mortised at 8 on their outside edges toreceive the tenons formed by the ribs 7 of the cross bars, these ribsbeine' of a width equal to the thickness of uprights 3 and thechannelled portions of the side frames; The channel 9 acts also as amortise to receive thelower end of the uprights 3, one side of thechannels being formed with bevelled or edging edges l0, which cooperatewith the wedges of the uprigg'hts as the cross bars are forced down andseated on the side bars to `cause the uprights and cross bars wedginglyto'interlock with the side bars. The cross bars 2 are locked by themortise and tenons 7-8 against looseningl movement lengthwise of theframe, and are rigidly held crosswise by theshoulders of the mortise 6engaging; opposite sides of the side bars. rIhe uprights 3 aremaintained in vertical position by the firm engagement of the lowerslotted ends with the sides of the mortise 6 of the cross bar and bythewedging interlock of its end edges with the sides of the mortise orchannel 9 of the side bar 1. The described construction, While aknockdown provides for a rigid construction when assembled andinterlocked as described. The upper ends of the uprights 3 are providedwith vertical notches 7 therein to receive the rock arms l2 formed byoffsets at the lil upper ends of the hanger for the swing itself. These'hangers are, preferably, in the form ot' strong metal rods, theupperends of which are laterally otl'set as .at 12 as described 'andVprovided with enlarged heads 13 to retain them inthe slots 11. Thehanger for the tor- Ward end of the swing is in the form, substantiallyotra U shaped bar ,L t'while the rhangerl for the rearV end ot the swingwhile o tfa ygenerally U-sha'pe 'is provided with a central crankportion i 16 bentupwardly from its lower ,end so that the portion 17between the .crankl and .theside bars of the hanger 15 constituterockshatts `or arms.

These hangers support a swingconstruction as follows: Runner bars 1Sextending longitudinally. of the .base frame and' arranged in parallel,have notches 19 formed at alined points on .their lower edges in whichthe cross bar 2O of the front hanger 14 .journalto support the runnersand in which the rock armsl? ofthe rear Ahangers 15 likewise i' seat andjournal. Intermediate the ends ot the runners 1 8, there are formedupward eX- tensions 21 forming a seat base. The upper edgeof this baseis provided with a pluralitgy7 Y of uniformly spaced sockets 22 intowhich seat studs23 projecting tromthe base of a bucket seat24,adjustably to position this seat longitudinallyon the ibase 21.Pivoted at 25 on the inner sides of the seat base 21 are hand levers 26connected by head. and nutat opposite ends of a cross rod 27 which .maybe said to form a handle bar, andv having pivotally mounted thereon,kadjacent to their lower ends, connecting bars 28,v the lrear ends ofwhichl are split, as seen in Figures land 2 at 29,` andbored yto providebearings Yfor the crank 16 ofV the hanger 15, bolts 30 retaining thecranks 16 in its' bearings atterthe same has been inserted Vthrough thesplit end 29. lTheV lower `ends Lot the handle bar levers 26 extendthrough slots 31 (Fig. 2) appropriately located in a foot board 32 whichis hung from theseat'base 21 and corners 1S'by appropriate stirrups 33,.the lower end of the handle bar levers'thereby connecting this footboard with the `levers so that toot pressure applied through thesuspended foot board 32 will cooperate with these levers and the crankbars128to Aoscillate the crank 16 and rock arm 1f? andcause the swing tomove to and fro. The stirrups-BS are Vinserted from the n bottom of lthefoot board rthrough appropriate apertures and areretained therein bybends at their "lower ends, correspondingly bent cising device todevelop their bodies. 'be no ted that vthe construction is such thatscribed, it is to be noted that I have inclined the pairs of front andrear uprights 3 toward each. other and upwardly i'rom their .'base..This, as will be seen from Figure 2 of the drawings, is for the purposeot positioning-the side bars of the hangers perpendicular to the tramesupport or base with the swing section centered therein. The han gersfor the swing section also act through their side bar and crank arms to.cross brace the runners 1S, these beingk additionally cross braced bythe spanning seat 211 superimposed on the upward extensions 21 ot therunners.

The described construction provides a low hung swing, especiallysuital'ile l'or children, both for amusementpurposes an d as an exer- Itwill both arms and legs are conjointly exercised in operating the swingsince the levers 2G are pushed forwardly and the toot board is pushedupwardly and baclnvardly by the seat occupant -lor actuation of theswing forwardly and the levers are pulled baclnvardly and the toot boarddownwardly and forwardly in the reverse movement of the swing, therebynaturally bracing the ieet and back lor the pull or thrust of the armsand giving complete muscular exercise. It will be obvious that the seat24 can be easily adjusted on its base -to tit the child to the swing toroperating purposes, and that the thrust on 'the levers 26 or connectinghandle bar 2T aided by foot pressure against the toot board or pedal 32is effective to cause the swing to oscillate to and tro with its hangersin their supporting trame. It will also be evident that thedescribed.construction may he disassembled and .packed piece-meal forshipment. This is true as to every portion ot the assembly, so that theminimum in the way oil nspace is required for packing. The simplicityolf the construction and the minimum ot bolts required makes itsassembly a comparatively easy matter.
